Method of processing data used in wireless applications using unstructured supplementary service data (USSD) and computer readable medium therefor

Abstract

A method for processing data, in a wireless application protocol for wireless applications using Unstructured Supplementary Service Data (USSD), includes the steps of: (a) receiving data from an upper layer into a Wireless Datagram Protocol (WDP) layer; (b) storing the data received in the WDP layer in step (a) in a common buffer which is commonly used by the WDP layer and a USSD Dialogue Control Protocol (UDCP) layer; and (c) forming packets in the UDCP layer using the data stored in the common buffer in step (b), and then transmitting the packets through the USSD. According to the method, memories for the WDP layer and the UDCP layer, which is an adaptation layer for a Global System for Mobile communication (GSM) USSD bearer, are integrated into one, effectively reducing a required memory size compared to conventional methods in which the WDP layer and the UDCP layer use separate memories.
